Step 1: Preparing your Mylar Heart Balloon

Take 150cm length of white curling ribbon. Measure 100cm and at that point fold it back over on itself, leaving the remaining 50cm for curling. Take 5cm of sticky tape and apply it to the folded section of ribbon (fig. 1).

Carefully attach it to the neck of the heart balloon, on the opposite side to the self-sealing filling valve (fig. 2).

Step 2: Inflating the Heart Balloon

O.K., let's start blowing up the balloon with helium. Gently insert the nozzle of your 'filling station valve' into the opening of the balloon self sealing valve (fig. 3). As you do this, take care not to use too much force in case you tear the mylar.

Keeping a firm grip with your thumb and index finger, begin inflating the balloon. The type of valve we are using here is commonly called a 'Quick Fill Station'. It works simply by applying downward pressure to the black flexible section. If you've never used one of these before, press it down very gently so that you get a slow, controlled release of the gas.

Continue to blow up the balloon until it begins to feel firm (fig. 4).

Step 3: Attaching the Heart Balloon to the Base

Tie the balloon ribbon to the nylon line of your pre-prepared base with two securing knots (fig. 5). The height of the heart should be roughly 80cm to 100cm.

Step 4: Preparing the Latex Balloons

Take the first of your white latex balloons, slip its neck gently over the valve of your 'filling station' and begin inflating (fig. 6). When the balloon is filled approximately to its optimal size, check it using your balloon sizer (fig. 7) and inflate or deflate as required.

When the balloon is the correct size then you tie a knot. Check out our "Tips & Tricks" for an easy and quick way make a balloon knot.
